SUMMARY:Number Theory Seminar
CLASS:PUBLIC
DESCRIPTION:J.C. SAUNDERS\, BEN GURION UNIVERSITY OF NEGEV\n\n\"Diophantine
  equations involving the Euler totient function\"\n\nWe deal with various 
 Diophantine equations involving the Euler totient\nfunction. In particular
 \, for $a\,b\,c\,m\,n\\in\\mathbb{N}$ with $m\\geq 2$\nwe study the equati
 ons $\\varphi(ax^m)=\\frac{b\\cdot n!}{c}$ and\n$\\varphi\\left(\\frac{b\\
 cdot n!}{c}\\right)=ax^m$ where $\\varphi(x)$ is\nthe Euler totient functi
 on. We also deal with similar equations\ninvolving Lucas sequences of the 
 first kind and second kind\,\ngeneralising the work of Luca and Stanica.
